Why is it that if I stand on a perfectly even train-track, the track appears to shrink in width the more distant it is away?

Question

Imagine your take a photo while standing on a train track pointing your camera in either direction of the perfectly even track. Now if you look at the photo. You would figure, that both individual metal parts of the track move closer together the farther they are away, creating some kind of “depth”(?). But I cant explain why that is.

It found it very odd to look at such a pictures in the last time, and started to question it. Why is our visual perception that kind of “distorted”?

I think reading and/or watching some videos about [parallax](https://en.wikipedia.org/wiki/Parallax) will be interesting to you, OP
